How Far Back Do You Cut Blackberry Bushes

You cut blackberry bushes back based on the type you’re growing and the season you’re in.
 
For most backyard gardeners, that means cutting floricanes (the canes that already fruited) all the way down to the ground after harvest.
 
If you’ve ever wondered how far back do you cut blackberry bushes, the short answer is: it depends on whether your blackberries are summer-bearing or everbearing.
 
Summer-bearing types get cut back hard after they finish fruiting, while everbearing types get a lighter trim in summer and a bigger cut in late winter.
 
In this post, we’ll break down exactly how far back to cut blackberry bushes, when to do it, and how to avoid the mistakes that cost you next year’s harvest.
 
Let’s dig in.
 

How Far Back Do You Cut Blackberry Bushes?

How far back do you cut blackberry bushes really comes down to one simple rule: remove the canes that already produced fruit, and leave the new ones alone.
 
Blackberries grow on a two-year cycle, meaning a cane grows one year, fruits the next, and then dies.
 
So when you cut blackberry bushes back, you’re basically clearing out the dead wood to make room for fresh growth.
 

1. Cut Fruiting Canes to Ground Level

The canes that gave you berries this year are done, and cutting blackberry bushes back to the ground is the cleanest way to handle them.
 
Grab your loppers and cut these floricanes as close to the soil as you can, leaving nothing but a tiny stub.
 
This is how far back you cut blackberry bushes that already fruited, and it stops them from hogging nutrients your new canes need.
 

2. Leave the New Primocanes Standing

The fresh green canes that grew this season are your future berry producers, so don’t touch them when you cut blackberry bushes back.
 
These primocanes will fruit next year, and cutting them now means zero blackberries next summer.
 
If they’re crowding each other, thin them to about four to six strong canes per plant instead of cutting them down.
 

3. Trim Side Branches on Healthy Canes

You can also cut blackberry bushes back by shortening the side shoots on your new canes.
 
Cut these lateral branches back to around 12 to 18 inches, which keeps the plant tidy and encourages bigger berries.
 
This is a lighter version of how far back to cut blackberry bushes, and it’s all about shaping rather than removing.
 

When to Cut Blackberry Bushes Back

Timing matters just as much as how far back do you cut blackberry bushes, so let’s talk about the right windows to do the job.
 

1. Right After Harvest for Summer-Bearing Types

For summer-bearing blackberries, the best time to cut blackberry bushes back is immediately after you pick the last berry.
 
The old canes are spent, and removing them right away gives the new growth more room, light, and airflow.
 
This is when you cut blackberry bushes back the hardest, taking those fruited canes straight to the ground.
 

2. Late Winter for Everbearing Types

Everbearing blackberries fruit twice, once in summer and again in fall, so you cut blackberry bushes back differently.
 
After the summer crop, you can cut blackberry bushes back by trimming just the tips that already fruited.
 
Then in late winter, cut blackberry bushes back to the ground to reset the plant for the new season.
 

3. Avoid Cutting During Frost

Never cut blackberry bushes back when a hard freeze is on the way, since fresh cuts are vulnerable to cold damage.
 
Wait until the worst of winter has passed, and always cut blackberry bushes back on a dry, mild day.
 
That way the plant heals fast and you don’t lose canes to dieback.
 

Tools and Tips for Cutting Blackberry Bushes Back

Knowing how far back do you cut blackberry bushes is one thing, but having the right approach makes the job way easier.
 

1. Wear Thick Gloves

Blackberry canes are covered in thorns, so thick leather gloves are non-negotiable when you cut blackberry bushes back.
 
Long sleeves and pants help too, because those thorns will find any bit of bare skin.
 

2. Use Sharp Loppers and Pruners

Sharp loppers make quick work of thick canes when you cut blackberry bushes back to the ground.
 
Use hand pruners for the smaller side shoots and loppers for the big floricanes.
 
Clean cuts heal faster, so sharpen your blades before you start cutting blackberry bushes back.
 

3. Dispose of the Cuttings

Once you cut blackberry bushes back, don’t leave the trimmings lying around the base of the plant.
 
Old canes can harbor pests and disease, so bag them up or burn them.
 
This keeps your patch healthy every time you cut blackberry bushes back.
 

So, How Far Back Do You Cut Blackberry Bushes?

You cut blackberry bushes back to the ground for canes that already fruited, and you leave the new canes standing to fruit next year.
 
For summer-bearing types, do this right after harvest, and for everbearing types, trim in summer and cut back hard in late winter.
 
So when someone asks how far back do you cut blackberry bushes, the answer is simple: remove the spent canes completely and protect the new ones.
 
Follow that rule and you’ll get a bigger, sweeter harvest season after season.
